Animated PNG to GIF

100 MB total; up to 20 PDFs to merge. Other PDF tools accept one file. Encrypted PDFs are unsupported. Signatures and interactive content may change. Cropping hides content; it is not secure redaction. Flattening supports form fields only. ZIP/TAR/TAR.GZ: 500 entries and 100 MB expanded. Images: 50 MB, first frame only; PNG quality is lossless. Compression may produce larger files.

Convert every animation frame locally, preserving centisecond durations and loop count. The separate default preview image is excluded. GIF quantizes colors and reduces partial transparency to a binary mask. Only non-interlaced 8-bit RGB/RGBA APNG is supported; ICC and unsupported chunks are rejected. · 15 MB input / 200 frames / ≤4 MP,2048 px per side / ≤60 MP total / 20–10000 ms per frame,multiple of10 ms / ≤120 s animation / ≤65536 plays / WASM≤256 MiB / GIF≤40 MB / 90 s conversion
